Module summary

All sports and exercise activities involve muscular activity. Therefore the biochemistry of exercise underpins the study of the factors that contribute to exercise and sports performance. To any one of us there is an upper limit to our ability to perform a task involving muscular effort. This applies to activities dependent on strength, speed, stamina or skill. The ability to respond to an acute exercise challenge and the capacity to respond to a training stimulus with an improvement in function are the keys to being successful in sport. This is true also in pathological conditions where exercise tolerance is limited. This module aims to elucidate the cellular biochemical events required during exercise and to discuss how these are modulated in response to exercise training for different tasks. The module will explore exercise responses including the role of muscle structure and function in allowing a weight lifter to perform extreme feats of strength or power; and the cellular metabolic pathways that allow elite marathon runners to sustain high work rates for prolonged durations. Pathological conditions that result in limited functioning of these processes will also be considered, and the genetic basis of athletic capability and training will be discussed.

Objectives

The objectives of the module are:
- To understand the structural and biochemical importance of metabolic pathways in exercise and how the body adapts to
different metabolic demand and stresses, as illustrated by sports training;
- To provide an understanding of genetic factors involved in structural and biochemical related pathology in exercise;
- To enable students to acquire the skills necessary to plan and execute practical investigation in biochemical processes
and to critically evaluate and interpret such data.

Learning outcomes
Knowledge of:
- Energy rich phosphates ATP, ADP, creatine phosphate;
- The structure of muscle and the biochemical basis of contraction;
- The importance of different metabolic processes involved in different exercise regimes (sprinter, endurance runner,
weight lifter);
- How genetic factors and disease can affect or determine ability in exercise and training.
